LENS-MOUNT FOR RIMLESS EYEGLASSES OR SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 675,957, dated June 11, 1901.

Application filed January 26, 1901. Serial No. 44,826. (No model.)

To @ZZ whom t may concern:

Be it known that I, ANsEL LEO, a subject of lIis Majesty the King ofGreat Britain, residing in the city and district of Montreal, Provinceof Quebec, Canada, have invented certain new and useful Improvements inLens- Mounts for Rimless Eyeglasses or Spectacles; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention is an improvement in rimless eyeglasses and spectacles, bywhich I secure a firm and secure connection between the lens and itsmount without cutting, abrading, or otherwise treating the lens in anymanner whatsoever.

It has long been recognized that drilling a hole in a lens isobjectionable from many standpoints, so that numerous attempts have beenmade to unite the lens and the mount byclainpsandotherforinsof devices.Among such prior attempts known to me there have been at least two inwhich it has been proposed to employ cement as a means for uniting theglass lens to the metallic mount; but owing to non-rigidity in the mountdue to its faulty construction the use of cement has not beenaccompanied by any substantial results.

It is my purpose to provide a mount of improved construction Which willafford the desired rigidity, stability, and strength, so as to enable anedge portion of the lens to be solidly and securely cemented thereto andat the same time to promote and cheapen the manufacture of the mount bymaking it possible to stamp the same from a single piece of sheetlnetal.

To the accomplishment of these ends the invention consists in the novelconstruction and arrangement of parts, as will be hereinafter fullydescribed and claimed.

In the drawings hereto annexed, forming a part of this specification,Figure l is an elevation of a pair of eyeglasses having the lensesthereof united to their mounts as contemplated by this invention. Fig. 2is detail view, on an enlarged scale, of one of the lensmounts,illustrating the blank form thereof. Fig. 3 is a detail perspective viewof one of the complete lens-mounts.

The same numerals of reference denote like parts in each of the severalfigures of the drawings.

5 designates the lenses, 6 the bridge-spring, 7 the nosepieces, and 8the mountings, of a pair of eyeglasses, all of which except themountings are of the usual or any preferred construction.

The important feature of my invention consists in the construction ofthe lnount 8, the same being represented more clearly by Fig. 3 of thedrawings. This mount is stamped or struck up in blank form from a singlepiece of sheet metal, as represented by Fig. 2 of the drawings, wherebythe mount may be manufactured economically and rapidly. It is necessaryin a lens-mount which contemplates dispensing with the ordinaryclamping-screw for the lens and the employment of cement as a fasteningmedium to make said mount present a stable rigid form or constructionand include large bearing-surfaces adapted forimpingement against theedge and lateral faces of lthe lens without, however, offering materialobstruction to the vision. These ends are attained in a mount of myconstruction, which mount is struck up in the form of a blank 9 from asingle piece of metal. This blank consists of a plate I0 and the wingsIl. Said plate has straight parallel edges 12 13, while the wings arecurved substantially as shown. The inner edges I4 of each wing extendinwardly toward the straight edges of the plate, so as to join therewithand leave the tapered openings or incisions. The outer edges I5 I6 ofeach wing extend from the curved edges 14 thereof toward each other andmeet in the point 18.

In the manufacture of the mount it is stamped according to the blank 9,and the plate l0 is then given alongitudinal curvature, as representedby Fig. 3, thus making the plate conform to the edge of the lens. Thewings 11 are bent so as to lie parallel to each other and in a plane atright angles to the plane of the curved plate l0, (see Fig. 3,) and theinner edges I4 of said wings are united to the straight edges of thelongitudinallycurved edge bearing-plate I0-as,for example, by solderingor brazing. The complete mount presents the appearance substantially asrepresented by Fig. 3, from an inspection of which it is apparent thatthe wings serve to strengthen and reinforce the edge bearingplate, andsaid wings also present large surfaces adapted to impinge against thelateral faces of the lens when said lens and the mou nt are assembledinto operative relation. The lens and the mount are united solidly andIirmly together by the employment of a quickhardening form of cement,which is applied over the entire surface of the plate 10 and thewings1l,so as to constitute aninnercoatingfor the mount and to adhereintimately to the lens and to the mount. The cement when freshly appliedpermits the lens to be adjusted edgewise within the mount before thesame becomes hard and set, thus enabling the optician to accuratelyadjust the lens in order to secure the proper fitting of the eyeglassesin accordance with an oculists prescription. The solidity and rigidityof the mount, in connection with the large surfaces afforded by thepeculiar shape of the wings, enable me to successfully unite a lens tothe mount by the aid of cement, thus attaining a result in thisparticular art which, to my knowledge, has not heretofore beensuccessfully accomplished. Vhile the wings of the mount affordrelatively large bearing-surfaces forengagement with the lens, it is tobe understood that the mount does not obstruct the vision in any way. Asa matter of fact, the mount is not visible to the wearer of theeyeglasses when the parts are properly assembled.

To provide for the attachment of the spring and nosepieces, a pillar orpost 19 is united to the outer face of the edge bearing-plate l0,

forming a part of the mount-as, for example, by soldering the post tothe mount. The post has a socket adapted to receive the spring 6 and apart of one nosepiece 7, which parts are held in place by the screw 20.The mount and the post may bc finished in any suitable style.

Although I have shown and described my improvement in connection witheyeglasses and as specially adapted for use in connection with thenosepiece and the spring, I would have it understood that the principleof the mount may be used in connection with the ring-handle which issometimes applied to eyeglasses and also in the construction ofspectacles.

Having thus described my invention, what I claim as new is- A lens-mountblank stamped in a single piece of sheet metal and comprising a centralelongated plate provided with straight parallel side edges, and thewings disposed on opposite sides of the plate and joined to the middleportions thereof, each wing having a convexly'curved inner edge whichextends outwardly from the line of juncture between said plate and thewings, whereby the plate may be bent to a longitudinally-curved contourand said curved edges of the wings may be soldered to the plate,substantially as described.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

ANSEL LEO.
